Evaluating State Endangered Species Lists

by John Beetham in A DC Birding Blog

Long-billed Curlew / Photo by Mike BairdAt a time when federal listings have been delayed and international standards are difficult to implement, state endangered species lists can play an important role in protecting at-risk species. That is, they can protect globally threatened species, especially ones for which their region bears high responsibility. Jeffrey Wells of the Boreal Songbird Initiative set out to assess how well state lists are identifying and protecting globally threatened specie........ Read more »

Scientists torn between cash and kudos

by sciencebase in Sciencebase Science Blog


With ailing banks propped up by billions in taxpayers’ money and nations rolling through the mud of economic recession is it any surprise that we get mightily frustrated to hear of their enormous bonuses and golden pension pots? Of course not… But, here’s a thought…

How far can a bee fly, and why should we care?

by Rob Goldstein in Conservation Maven

Entomologists from Switzerland have published a study that measures how far three different species of bees can fly to forage for food. Their study is innovative because it uses a new, direct experimental approach in which patches of host plants were moved progressively farther back from the nest over time. Antonia Zurbuchen and fellow authors measured the number of female bees that were able to forage at the patch at each distance. This research question is crucial for addressing the widespread........

Cuttlefish camouflage split decision

by Zen Faulkes in NeuroDojo

As I've written about before, cephalopods are the masters of camouflage. But what happens if they have to try to match two different backgrounds? Allen and colleague (containing several members who worked on the paper I wrote about earlier) tackle this problem with cuttlefish (Sepia officinalis).

There's a couple of possibilities. Because octopus and squid and such can control colour on each half of their body independently, they'll try to match both sides. Another possibility is........ Read more »

Roller Coasters Can Be Such A Headache

by The Neurocritic in The Neurocritic

Dodonpa roller coaster, 170 feet tall, 106.9 mph. Located in Fuji-Q Highland amusement park in Japan.In case you didn't know, there's a reasonably sized literature on roller coaster headaches. An especially interesting case was reported by Fukutake and colleagues (2000) in Japan. A 24 year old woman frequently visited amusement parks, including Fuji-Q Highland -- home to 3 monster roller coasters (she rode each of them twice):One of these, the Fujiyama, is the world’s highest roller coaster at........

Atonement, self-punishment, and guilt

by Tom Rees in Epiphenom

Atonement is a funny concept. Essentially, it's the idea that you can cancel out a wrongdoing not by doing a good deed, but by engaging in some act of self-punishment.Although the classic example comes from Christianity (the tortured death of Jesus) similar concepts of penance are widespread in other religions. Penance goes beyond the more normal concepts of justice (revenge and punishment) because it's voluntary.Perhaps there's more going on here than meets the eye. Rob Nelissen and Marcel Zeel........

Ancient Tracks Question Ideas About Tetrapod Origins

by Laelaps in Laelaps



Tiktaalik is practically a household name. Since its description in 2006 the flat-headed "fishapod" has appeared in books, on t-shirts, and has even starred in its own music video. Hailed as a "missing link", Tiktaalik has become a poster child fossil for evolution, but it is hardly the first such creature to be given this honor.

Looking to the Jersey Shore for CO2 sequestration

Riding on the heels of Copenhagen, a study published yesterday in the Proceedings of the National Academy of Sciences outlined one way the United States might address enormous CO2 emission levels. Not surprisingly, the researchers propose carbon sequestration; it is the location, however, that makes this study unique.
The scientists have pinpointed volcanic rock, namely [...]

A new paper just showed up on PLoS One and it has some serious potential to be important The paper (PLoS ONE: The Effects of Circumcision on the Penis Microbiome) reports on analyses that show differences in the microbiota (which they call the microbiome - basically what bacterial species were present) in men before and after circumcision.

Finding Recurrent CNVs in Cancer

by Daniel Koboldt in Massgenomics

Copy number aberrations (CNAs) represent one of the most prevalent genetic alterations in cancer cells. There is considerable interest in finding CNAs that affect the same chromosomal region in multiple tumor samples. Recurrent CNA (RCNA) implies the presence of key cancer genes; on chromosome 7, for example, we often see amplification of the region containing [...]... Read more »

Reduced Sleep Means Reduced Physical Activity

by Travis Saunders, MSc in Obesity Panacea

In the past, I have mentioned that physical activity and sleep time are positively related - the more physical activity you perform, the more sleep you are likely to get. Now most of these past studies have been observational, so we have a bit of a chicken and egg problem. By that I mean that we don't know whether:

A) Sleep deprivation causes reductions in physical activity,
B) High levels of physical activity make people sleepier, or
C) Some combination of A & B

Fortunately, an in........ Read more »
